4-66 Sun Fire V20z and Sun Fire V40z Servers—User Guide • March 2005
For the SCSI backplane power cable and the SCSI signal cable, you should remove
the following components:
■ main air baffle
■ rear fan-cage assembly
■ individual power supplies and power-supply cage assembly
Refer to the sub-section in the procedure for the components to remove and for each
type of system cable to replace.
1. Power off the server, including any attached peripherals, and disconnect the
server from the electrical outlet. If your server includes two power supplies,
ensure that both power cords are disconnected from the electrical outlet.
Refer to “Powering Off the Server and Removing the Cover” on page 4-2.
2. Remove the main air baffle (see
FIGURE 4-20).
Lift the rear edge of the baffle, then move it toward the rear of the server to
disengage the hooks on the front edge of the baffle.
Rear Fan-Cage Assembly
3. Remove the rear fan-cage assembly. Squeeze inward the retainer clips on each end
of the rear fan-cage assembly (see
FIGURE 4-25).
4. Pull straight up on the fan-cage assembly to disengage it from the motherboard
connector.
5. Lift the assembly up and out of the server.
Individual Power Supply
6. Remove the individual power supplies. At the outside rear of the server, pull the
finger-ring on the power-supply handle toward you to disengage the
power-supply connector from the power distribution backplane (see
FIGURE 4-26).
Note – A twisted, plastic tie-wrap through the finger ring holds the power-supply
handle in place. Untwist this tie-wrap to pull the handle out.
7. Slide the power supply out of the power-supply cage and chassis.
